You cant get that, its a little bit like s775, but not

to get higher Ram speed, you have to get higher Bclk, you can if you dont want so high cpu klock, lower cpu multiple, put 200 bclk
and then get either 1600 at 8x, 2000 at 10x.

The uneaven ram speed do work ofc, just put like 150bclk, then use maybe 12x multiple.. and ofc if you put 154bclk, you will not get eaven ramspeed..Even bclk becomes even ramspeed, and uneaven will become uneaven.

just try, you dont have to save and exit just to see what the desired speed will be.

EDIT: saw that it looked little weird, but you get it dont ya?
